BACKGROUND OF THE INVENTION

[0001] To color human or animal hair using conventional oxidative dyetechnology it is generally necessary to treat the hair with a mixture ofsuitable oxidative coloring agents and at least one oxidizing agent andswelling agent at alkaline pHs. Hydrogen peroxide is the most commonlyused oxidizing agent. However, there is a recognized need to develophair care compositions which more effectively deliver hair color. It isa purpose of the present invention to provide such a hair coloringcomposition.

[0002] The following publications relate to the field of the invention:

[0003] U.S. Pat. No. 5,131,912 discloses durable 2-part hair dyeingagents composed of a first agent comprising as essential components atleast one compound that forms HCO₃—by dissociation in water, an alkaligenerating substantially no irritating odor and a dye for hair andhaving a pH of 8.2 to 9.0. and a second agent comprising as essentialcomponents hydrogen peroxide and a buffer solution and having a pH of2.0 to 4.0, the weight ratio of the first agent and the second agent tobe mixed being such that the pH of the mixture of the two is in a rangeof from 6.5 to 7.9. These 2-part hair dyeing agents require only a shortdyeing time, create little damage to hair and no irritating ordisagreeable odor and have high dyeing effect.

[0008] As used herein, % means weight % of the total composition unlessotherwise designated. The compositions of the invention are made usingknown ingredients or with ingredients analogous to those known in theart. The packages or containers to be used with the compositions of theinvention are made using known processes and materials or by processesand materials which are analogous to those known in the art.

[0009] Compositions of the invention are used in a one step process forthe coloring and bleaching of hair. That is, the composition is made bymixing the following two ingredients just prior to application to thehair;

[0010] (a) a composition comprising a water-soluble peroxygen oxidizingagent; and

[0011] (b) a composition comprising one or more oxidative hair coloringagents selected from the group consisting of an aromatic diamine, anamino phenol, a naphthol, a polyhydric phenol, a catechol and mixturesthereof; wherein the composition comprising one or more oxidative haircoloring agents further comprises al least one water soluble carbonatereleasing salts; and optionally a water soluble ammonium salt.

[0012] After mixture, this composition is then applied to hair. Thiscomposition is allowed to remain on the hair for about 2 minutes toabout 60 minutes. The coloring reaction takes place and the hair isrinsed.

[0013] As used herein the term “hair” to be treated may be “living” i.e.on a living body or may be “non-living” i.e. in a wig, hairpiece orother aggregation of non-living fibres. Mammalian, preferably human hairis preferred. However wool, fur and other melanin containing fibres aresuitable substrates for the compositions according to the presentinvention.

[0014] The hair coloring compositions can contain, in addition to amixture of active oxidizing agents and oxidative coloring agents,ingredients such as, by way of example, sequestrants, thickeners,buffers, carriers, surfactants, solvents, antioxidants. polymers,non-oxidative dyes and conditioners.

[0015] As noted above, there is provided a hair coloring compositionwhich comprises the following two compositions which are mixed justprior to application to the hair:

[0016] (a) a composition comprising a water-soluble peroxygen oxidizingagent; and

[0017] (b) a composition comprising one or more oxidative hair coloringagents selected from the group consisting of an aromatic diamine, anamino phenol, a naphthol, a polyhydric phenol, a catechol and mixturesthereof; wherein the composition comprising one or more oxidative haircoloring agents further comprises at least one water soluble carbonatereleasing salt; and optionally a water soluble ammonium salt.

[0018] The water-soluble peroxygen oxidizing agent may be selected fromhydrogen peroxide, sodium perborate, sodium percarbonate, and ureaperoxide complexes.

[0019] The composition comprising a water-soluble peroxygen oxidizingagent may further comprises a buffering agent.

[0020] The mixture of the composition comprising water-soluble peroxygenoxidizing agent and the composition having one or more oxidative haircoloring agents as described above has a pH of about 8 to about 11.

[0021] The composition having one or more oxidative hair coloring agentsand the composition comprising a water-soluble peroxygen oxidizing agentmay further comprises a surfactant selected from the group consisting ofanionic, nonionic, cationic, zwitterionic, amphoteric surfactants andmixtures thereof.

[0022] The invention also relates to a hair coloring kit comprising anindividually packaged oxidizing component with additional agents, anindividually packaged component having one or more oxidative haircoloring agents which when mixed forms a composition of the invention.

[0023] The invention also relates to a process for coloring human oranimal hair which comprises applying to the hair the compositionsdescribed above.

[0024] Change in hair color can be measured by means which are known inthe art. A customary scale for measuring the change in hair color isdefined in terms of the variables: L, a, and b wherein L, a, and b aredefined as follows: L indicates the lightness or darkness of the colorvalue. The higher the L, therefore, the lighter the hair, and the morefading that has occurred. When L is 0, the hair is black, and when L is100, the hair is white. −a and +a represent changes in color tone fromgreen to red. −b and +b represent the changes in color tone from blue toyellow.

[0025] What follows now is a description of the ingredients which may beused in the compositions of the invention.

[0026] Water-Soluble Peroxygen Oxidizing Agents

[0027] The compositions of the invention may comprise at least onewater-soluble peroxygen oxidizing agent. Water-soluble as defined hereinmeans a peroxygen oxidizing agent compound, which can be substantiallysolubilized in water.

[0028] The peroxygen oxidizing agents useful herein are generallyinorganic peroxygen materials capable of yielding hydrogen peroxide inan aqueous solution. Water-soluble peroxygen oxidizing compounds arewell known in the art and include hydrogen peroxide, inorganic alkalimetal peroxides such as sodium periodate and sodium peroxide and organicperoxides such as urea peroxide, melamine peroxide, and inorganicperhydrate salt oxidizing compounds, such as the alkali metal salts ofperborates, percarbonates, perphosphates, persilicates, persulphates andthe like. These inorganic perhydrate salts may be incorporated asmonohydrates, tetrahydrates, and the like. Mixtures of two or more suchoxidizing agents can be used if desired. Preferred for use in thecompositions according to the present invention is hydrogen peroxide.

[0029] Oxidative Hair Coloring Agents

[0030] The compositions of the present invention may include one or moreoxidative hair coloring agents. Such oxidative hair coloring agents areused in combination with the oxidizing systems of the present inventionto formulate permanent, hair dye compositions.

[0031] Permanent hair dye compositions as described herein arecompositions, which once applied to the hair are substantially resistantto wash-out. Wash-out as described herein is the process by which haircolor is removed from the hair over time during normal hair cleansingregimen.

[0032] When compared against a combination of all of the compositions ofthe invention after they have been mixed together, the concentration ofeach oxidative hair coloring agent is from about 0.0001% to about 7% byweight and is preferably from about 0.001% to about 2.0% by weight.

[0033] When compared against a combination of all of the compositions ofthe invention after they have been mixed together, the total combinedlevel of oxidative hair coloring agents in the compositions according tothe present invention is from about 0.01% to about 15%, preferably fromabout 0.01% to about 10%, more preferably from about 0.1% to about 5% byweight.

[0034] Oxidative hair coloring agents which can be used in compositionsof the invention can be selected from the group consisting of anaromatic diamine, an aminophenol, a polyhydric phenol, a naphthol, acatechol and mixtures thereof. Oxidative hair coloring agents which canalso be called oxidative dyes are described in more detail below.

[0035] The dye forming intermediates used in oxidative dyes can bearomatic diamines, aminophenols and their derivatives. These dye-formingintermediates can be classified as; primary and secondary intermediates.Primary intermediates are chemical compounds, which by themselves willform a dye upon oxidation. The secondary intermediates, are also knownas color modifiers or couplers and are used with other intermediates forspecific color effects or to stabilize the color.

[0036] The oxidation dye intermediates which are suitable for use in thecompositions and processes herein include aromatic diamines, polyhydricphenols, aminophenols and derivatives of these aromatic compounds (e.g.,N-substituted derivatives of the amines, and ethers of the phenols).Primary oxidation dye intermediates are generally colorless moleculesprior to oxidation. The oxidation dye color is generated when theprimary intermediate is activated and subsequently joined with asecondary intermediate (coupling agent), which is also generallycolorless, to form a colored, conjugated molecule.

[0037] In general terms, oxidation hair dye precursors or intermediatesinclude those monomeric materials which, on oxidation, form oligomers orpolymers having extended conjugated systems of electrons in theirmolecular structure. Because of the new electronic structure, theresultant oligomers and polymers exhibit a shift in their electronicspectra to the visible range and appear colored. For example, oxidationdye precursors capable of forming colored polymers include materialssuch as aniline, which has a single functional group and which, onoxidation, forms a series of conjugated imines and quinoid dimers,trimers, and the like, ranging in color from green to black. Compoundssuch as p-phenylenediamine, which has two functional groups, are capableof oxidative polymerization to yield higher molecular weight coloredmaterials having extended conjugated electron systems. Color modifiers(couplers), such as those detailed hereinafter, are preferably used inconjunction with the oxidation dye precursors herein. A representativelist of oxidation dye precursors suitable for use is found in Sagarin,“Cosmetic Science and Technology Interscience, Special Edn. Vol 2 pages308 to 310, which is hereby incorporated by reference.

[0038] The typical aromatic diamines, polyhydric phenols, naphthols,aminophenols, and derivatives thereof, described above as primary dyeprecursors can also have additional substituents on the aromatic ring,e.g. halogen, aldehyde, carboxylic acid, nitro, sulfonic acid andsubstituted and unsubstituted hydrocarbon groups, as well as additionalsubstituents on the amino nitrogen and on the phenolic oxygen, e.g.substituted and unsubstituted alkyl and aryl groups.
